Focusrite ISA Two

This is just great on drums and acoustic guitars. Punchy, warm, clear and a dark "weight" down below. It's not THAT coloured, so you can use it on anything with good results. For stereo micing it's great to have the stepped gain knobs, phase switches etc. There is plenty of gain, the 3 impedance options are sometimes useful, as is the HP filter knob. I have two of them in regular use with no issues whatsoever.
